The video ends with the student grabbing a five-dollar bill and holding it up to the camera to display the face of President Abraham Lincoln, saying: “This guy is a traitor to the white race.”

The video emerged amid a nationwide discussion on race in America’s public classrooms and college campuses, one that gained steam after racial tensions at the University of Missouri last fall led to massive protests, a near-boycott by the school’s football team and the resignation of the administration’s president and chancellor. Students at colleges nationwide in recent months have been vocal about pushing for meaningful change to what they see as institutional racism.

The Baltimore Sun reports that the student has apologized on his Facebook page, writing that his statements were “racist, ignorant and overall an awful thing to say and to do…. I hope to learn from this mistake as well as not let it define who I am as a person.”

Howard County Schools Superintendent Renee Foose says the school’s “principal and members of the school administration are investigating the incident, and conferences are being scheduled with the involved students and their parents,” reports the Sun.
